• 简单的css缩放动画,仿腾讯新闻的分享按钮和美团app底部的图标样式


    最近看到一些好看的hover的图形缩放效果。然后自己就写了下,发现这2种效果都不错。如果伙伴们更好的实现方式可以在下面留言哦~

    还有美团的效果,我就不展示了,喜欢的可以去app应用上看看。

    这两种效果,其实实现的原理是一样的,就是用伪类选择器改变背景大小/图片大小。加一个过渡

        <!--腾讯新闻效果-->
        <a href="javascript:void(0);"  class="hover-body  hover-body-weixin">
            <i></i>
            <span></span>
        </a>
        <!--美图APP效果-->
        <a href="javascript:void(0);"  class="hover-body-app  third-party-app">
            <i></i>
        </a>

    腾讯新闻小logo:外部的a标签实现点击跳转,我这里设置不跳转,i标签使用伪元素代表前景色和背景色,伪元素定位在里面,然后用缩放属性,在伪元素后面放过渡效果

    .hover-body {
      position: relative;
      display: inline-block;
      width: 48px;
      height: 48px;
    }
    
    .hover-body:hover i::after {
      transform: scale(1);
    }
    
    .hover-body span {
      position: relative;
      display: block;
      width: 48px;
      height: 48px;
      background-size: 30px;
      background-position: center;
      background-repeat: no-repeat;
    }
    
    .hover-body i {
      position: absolute;
      top: 0;
      left: 0;
      width: 48px;
      height: 48px;
    }
    
    .hover-body i::before {
      content: '';
      border-radius: 50%;
      position: absolute;
      top: 0;
      left: 0;
      right: 0;
      bottom: 0;
    }
    
    .hover-body i::after {
      content: '';
      transition: all .3s;
      border-radius: 50%;
      position: absolute;
      top: 0;
      left: 0;
      right: 0;
      bottom: 0;
      transform: scale(0);
    }
    
    .hover-body.hover-body-weixin span {
      background-image: url(index.png);
    }
    
    .hover-body.hover-body-weixin i::before {
      background-color: pink;
    }
    
    .hover-body.hover-body-weixin i::after {
      background-color: palegoldenrod;
    }

    美团app仿效果:css,直接在i标签里放背景图片,设置伪元素before和after为2张图片,给图片放大小,加过渡

    .hover-body-app{
        position: relative;
        display: inline-block;
        width: 48px;
        height: 48px;
        margin-left: 6%;
        margin-right: 6%;
    }
    .hover-body-app:hover  i::after{
        transform: scale(1);
    }
    
    .hover-body-app i{
        position: absolute;
        top: 0;
        left: 0;
        width: 48px;
        height: 48px;
    }
    .hover-body-app i::before{
        content: '';
        border-radius: 50%;
        position: absolute;
        top: 0;
        left: 0;
        right: 0;
        bottom: 0;
    }
    .hover-body-app i::after {
        content: '';
        transition: all .3s;
        border-radius: 50%;
        position: absolute;
        top: 0;
        left: 0;
        right: 0;
        bottom: 0;
        transform: scale(0);
    }
    
    .hover-body-app.third-party-app i::before {
        background: url(index.png);
        background-size: 30px;
        background-position: center;
        background-repeat: no-repeat;
    }
    
    .hover-body-app.third-party-app i::after {
        background: url(indexfull.png);
        background-size: 30px;
        background-position: center;
        background-repeat: no-repeat;
    }
